Cleansing lotion with moisturising, protecting and odor controlling agents and cloth comprising said lotion

ABSTRACT

The invention relates to a soothing lotion, which cleanses, moisturizes and protects the skin and controls odor from feces and urine on skin. The invention also relates to a cloth comprising said lotion.

FIELD OF THE INVENTION

The invention relates to a soothing lotion, which cleanses, moisturizesand protects the skin and controls odor from feces and urine on skin.The invention also relates to a cloth comprising said lotion.

BACKGROUND OF THE INVENTION

Baza Cleanse & Protect® with Odor Control is a well-known cleansinglotion comprising dimethicone as a skin protectant. For easy applicationto the skin, the product is typically provided in spray bottles.However, due to the reverse thixotrophic property of the lotion,plugging of the nozzle of the spray bottle can be a re-occurringproblem.

It has now been found that it is possible to alter the recipe for theBaza Cleanse & Protect® with Odor Control to provide a new lotion withgood odor control having a lower viscosity, which does not causeplugging of the nozzle in spray bottles.

It has also been found that the new lotion with lower viscosity mayeasily be incorporated in a cloth or wipe fabric. Lotions with higherviscosity may not be as easily incorporated into a cloth or wipe fabric.

Sage Products, Inc. and Medline Industries, Inc. market disposablewashcloths comprising dimethicone. The disposable washcloth from SageProducts, Inc. is known as Sage® Comfort™ Shield™ Perineal-CareWashcloths, which comprises 3% dimethicone in a rayon/polyester blendneedle-punch cloth. The product from Medline Industries, Inc. is knownas Aloetouch One-Step Total Perineal Care, which comprises 3.2%dimethicone in a thin non-needlepunch cloth of a rayon/polyester blend.

It is well known in the industry, that rayon is blended with polyesterto enhance absorption characteristics. A disadvantage of using apolyester/rayon blend can be that a cloth of a polyester/rayon blendcomprising a cleansing lotion may tend to not release as much lotion toa surface during a cleansing event as a cloth comprised of 100%polyester.

It has been found that the new lotion of the invention is particularlysuitable for incorporation into cloths or wipe fabric for preparingproducts useful for cleaning the surface, in particular the skin of aliving being, and for controlling the odor from feces and urine on theskin, and for further providing a protective barrier to the skin.

In addition needle-punch cloth made of 100% polyester has been found tobe particularly useful as it is capable of delivering twice as muchlotion to the skin compared to the above mentioned polyester/rayonblended products, and is capable of maintaining comparable absorptioncharacteristics.

SUMMARY OF THE INVENTION

Accordingly, the present invention relates to a cleansing lotion in theform of an emulsion comprising 75-85% w/w water, one or more skinprotectants, such as dimethicone, one or more cleansing agents, and oneor more odor control agents where the viscosity of the lotion is below50,000 centipoise (cps) when measured on a Brookfield Digital viscometermodels DV-1+ and DV-11+ at a temperature of 25° C.±1° C., using spindleT-C at a speed of 1.5 rpm.

The invention also relates to a cloth and a spray bottle comprising thenew lotion. In particular the invention relates to a needle-punch, 100%polyester fiber cloth comprising the above mentioned lotion.

DETAILED DESCRIPTION OF THE INVENTION

Baza Cleanse & Protect® with Odor Control is a well-known cleansinglotion comprising dimethicone as a skin protectant agent.

It has been found, that by lowering the amount of cetearyl alcohol from3% w/w and in particular by lowering the amount of zinc ricinoleate from1% w/w in the known product, a lotion in the form of a stable emulsionwith a viscosity suitable for incorporation of the lotion into a clothmay be obtained.

Surprisingly, it has been found that a good odor control may be achievedeven when the amount of zinc ricinoleate is reduced considerably by theuse of fragrances, such as Ordenone™. Ordenone™ is a fragrance availablefrom Belle Aire Fragrances, Inc.

Accordingly, the present invention relates to a cleansing lotion in theform of an emulsion comprising 75-85% w/w water, one or more skinprotectants, such as dimethicone, one or more cleansing agents, and oneor more odor control agents where the viscosity of the lotion is below50,000 centipoise (cps) as measured on a Brookfield Digital viscometermodels DV-1+ and DV-11+ at a temperature of 25° C.±1° C., using spindleT-C at a speed of 1.5 rpm.

In a preferred embodiment of the invention, the cleansing lotion asabove comprises zinc ricinoleate as an odor control agent and the amountof zinc ricinoleate in the lotion is below 1% w/w.

According to one embodiment of the invention, the new lotion compriseswater, one or more emulsifiers or emulsion stabilizers, one or more skinprotectants, such as dimethicone, one or more humectants, one or moreemollients, one or more skin conditioners, one or more cleansing agents,one or more odor control agents, one or more preservatives, andoptionally one or more pH controlling agents, in the form of anemulsion, where the composition comprises zinc ricinoleate as an odorcontrol agent and the zinc ricinoleate is present in an amount below 1%w/w.

Suitably, the cleansing lotion of the invention comprises 75 to 85% w/wwater, 3.0-5.5% w/w of one or more emulsifiers or emulsion stabilizers,1-3% w/w of one or more skin protectants, such as dimethicone, 1-4% w/wof one or more humectants, 4-7% w/w of one or more emollients, 0.5-4%w/w of one or more skin conditioners, 1-3% w/w of one or more cleansingagents, 0.01-1.0% % w/w of one or more odor control agents, 0.42-0.8%w/w of one or more preservatives, and optionally one or more pHcontrolling agents. Preferably, the cleansing lotion as above comprises1-3% w/w dimethicone.

The cleansing lotion of the invention may comprise cetearyl alcohol andglyceryl stearate as emulsifiers or emulsion stabilizers, isopropylpalmitate and glycine soja (soybean oil) as emollients, glycerin andpanthenol as humectants, sodium lauroyl lactylate and propylene glycolas cleansing agent, allantoin and tocopheryl acetate as skinconditioners, methylparaben, propylparaben and diazolidinyl urea aspreservatives, zinc ricinoleate, Ordenone™ and fragrance as odor controlagents, and citric acid as pH controlling agent.

According to a preferred embodiment of the invention, the amount ofcetearyl alcohol is below 3% w/w.

In the new recipe the amount of diazolidinyl urea may be also increasedfrom 0.15% w/w to for example 0.30% w/w, compared to Baza Cleanse &Protect® with Odor Control.

Suitably, the cleansing lotion of the invention comprises 0.005-0.9% w/wzinc ricinoleate, suitably 0.005-0.1% w/w zinc ricinoleate, morepreferred 0.005-0.05% w/w zinc ricinoleate, and most preferred 0.01% w/wzinc ricinoleate.

The lotion of the invention suitably comprises 0.1-0.5% w/w Ordenone™,preferably 0.1-0.3% w/w Ordenone™ or most preferred 0.2% w/w Ordenone™.

Thus, according to one preferred embodiment of the invention, thecleansing lotion comprises 0.005-0.05 w/w zinc ricinoleate, 0.1-0.5% w/wOrdenone™ and optionally an additional fragrance. If present, theadditional fragrance is present in an amount of 0.1-0.3% W/w.

According to another preferred embodiment of the invention, thecleansing lotion comprises 0.005-0.05 w/w zinc ricinoleate, 0.1-0.3% w/wOrdenone™ and optionally an additional fragrance. If present, theadditional fragrance is present in an amount of 0.1-0.3% w/w.
